No matter what, Klein cannot be always unreasonable and let only Calix try to make things work
"W-what I mean is... I-I'm also a man... I a-also have u-urges and I might not be able to s-stop myself to d-do... t-things" Klein clarified with a soft tone. He was even stuttering from his nervousness
His honesty made Calix blush as he didn't expect Klein would actually say something like that
Fortunately, honesty cleared everything and Calix understood most of Klein's reason
"Cough... y-you don't need to hold back. I can accept whatever you could give whether it be small or.. g-going all the way"
Calix doesn't know why but this topic also makes him a bit shy. Maybe, most humans in their nature are really just shy when talking about this type of topic
